Hello everyone, I am Lao Yang.
A group of friends came out recently and asked me, what brand and model should a company buy if it wants to purchase a router/switch?
Or, if you want to buy a router/computer for your home, what is the most cost-effective?
I really want to make a complaint. If you keep asking, I will transform into a blogger with goods.
After discussing with the editorial department, in order to satisfy your wishes, I reluctantly compiled a small Amway post. Buying more is more risky, so you need to be cautious when buying. Remember, rational consumption is the first priority.

01 Network Equipment Selection Guide
When it comes to Amway, it is inevitable to talk about what constitutes good equipment and what is the criteria for judging.
We can judge from several dimensions. Like, do you want home or business use?
Want something more robust, or more technologically advanced?
Do you want a cost-effective product, or a face-to-face product?
And so on, let's clarify our purchase needs first.
From the brand point of view, there are many domestic manufacturers. If they want to buy equipment, many people will choose more common brands to start with. At present, mainstream commercial data communication brands include Huawei, H3C, Ruijie, and Sundray. Security equipment brands include Sangfor, Shanshi, Juniper et al.
As for how to choose routers and switches, I can also talk to you.
The reference values for enterprise routers are different from those for home use. Enterprise-level routers mainly look at these aspects: stability, functionality, and capacity.
The amount of hosts can be understood as the load, including all Internet devices, such as desktops, laptops, mobile phones, servers, etc. If the total number is 100, then choose more than 100 hosts.
Generally, companies will use broadband superposition or multi-dial, Internet behavior management, VPN establishment, flow control and other functions, which should also be noted.
In addition, some basic common-sense judgments, such as the matching of port types and the limitation of access bandwidth, should be paid attention to.
A good router can be judged by three conditions:
1. Full Gigabit WAN/LAN port;
2. Support 802.11ac (that is, 5G Wi-Fi as it is often said);
3. The number of devices is more than 30. In order to ensure the smooth flow of the network, it is recommended to choose a router with dual-core 1GHz+128MB memory. In addition, soft routing + AP is a good choice.
Looking at the switch again, the main parameters for core switch selection are: scalability, forwarding rate, backplane bandwidth, four-layer switching, system redundancy, etc.
How to choose a switch brand mainly depends on the applicable scenarios.
For example, if you are building a network for online shopping, then you will have very strict requirements on the processing speed of the switch, which requires a large amount of concurrent traffic without lagging.
If you are building a bank's network, then you can definitely accept some network delays, but you must ensure accurate data transmission. In transaction scenarios, there are almost abnormal requirements for "stability".
At present, the parameter data of many non-brand switches are very good, especially the packet forwarding rate and backplane bandwidth, but they are not good for use, so the purchase of switches still depends on the brand.
Domestic switch manufacturers such as Huawei, H3C, Ruijie, etc. are representative brands in the data communication industry, focusing on mid-to-high end, mainly in enterprise networks, operator networks, Internet and other scenarios.
Dahua is developing switch products around the characteristics of security scenarios.
The above brands have a good reputation in the industry. All in all, according to business requirements, it is best to choose the one that suits your project.
As for the detailed content, I have published a detailed version in this " The Most Complete Purchasing Guide for Network Equipment (Cost-Effective Version) ". Friends who want to read it can click on it and study it carefully.
02 618 Wanggong good things Amway
After talking about how to choose, the children in the editorial department also picked out some network equipment and books with beautiful prices in the 618 event, hoping to help you.
01 router
The price of a home router ranges from a few hundred yuan for the entry-level to a thousand yuan for the high-end, and you can choose according to your own needs.
If you are a small-sized family, you only need to buy one router, and the installation and configuration are simple.
If it is a medium-sized house, it is recommended to use 2 routers to form a MESH, which has wider and more stable coverage.
If you are a large-scale villa with a lot of money, I suggest you deploy the whole house network cable, choose the AP solution or the wired MESH solution, which requires multiple devices for network coverage.
The following recommendations are based on JD’s sales rankings, please choose wisely:
TP-LINK Avenue AX3000
Xiaomi Router AX6000
TP-LINK AC1200
Huawei AX3pro
Mi Router 7000
Huawei whole house wifi6 set Pro version
H3C (H3C) Whole House WiFi Set
The above recommendations are the best sellers, covering all price points.
For example, the AX6000 is equipped with a 2500M rate network port this time, which is a configuration that only current flagship routers have.
In terms of speed, AX3 Pro basically covers and even far exceeds the broadband speed of most ordinary households.
Xiaomi Router 7000 supports NFC one-touch networking. When friends come to visit at home, they only need to stick their mobile phones to the router to connect to the Internet.
In a large-scale network construction (villa, company, hotel, etc.), especially for buildings with different layers, seamless network switching is required in the house. The best way is to use a whole-house router, while reducing the number of different locations. Router investment and management can also eliminate the need for power cords.
In this regard, the product attributes can be satisfied. Huawei and H3C are still on the market. Huawei whole house wifi6 package Pro version and H3C whole house WiFi set are their stars. product, it is recommended to start with.
02 switch
The top ten brands of network switches are Huawei, Cisco, H3C, Ruijie, Prolink, JUNIPER NETWORKS, Aruba, ZTE, NETGEAR and D-Link.
If you want to choose a switch, start with the brand first.
Next, if you still want to judge, it is recommended to refer to the first point of the article to choose.
The following models are selected based on online reviews, and I hope fans and friends can make rational references.

03 Cloud series products
The cloud computing market has been booming in the past two years. This time 618, we can also see the clues - after all, this time, it is the first public price comparison war.
Alibaba Cloud, Tencent Cloud, Mobile Cloud, and JD Cloud have all joined the 618 battle. This price reduction can indeed be discussed.
The core of JD Cloud’s price reduction this time is not to promise how much the price of certain products will be reduced, but to ensure that the price of similar cloud products JD Cloud is the most favorable by means of “comparing prices across the entire network, and paying for the expensive one”.
Specifically, JD Cloud promises that the list price on the official website of all its core products is lower than the price listed on the official website of a specific cloud manufacturer.
According to the official website of Alibaba Cloud, the prices of some ECS products will be adjusted, with a maximum drop of 32.5%. The new prices will come into effect on June 6.
The price of Alibaba Cloud's core products has been cut by 15%-50% across the board, and the price of storage products has been cut by up to 50%. Since then, Alibaba Cloud once again announced that the number of free trial products has increased to more than 80, including cloud native, AI, security and other categories.
Mobile Cloud announced that it will reduce the price of a variety of cloud products. The general-purpose entry-level cloud host and the general-purpose network-optimized cloud host will all be cut by 60%, down to 240 yuan and 806.4 yuan per year respectively; the price of the cloud security center will be cut by 50% to 360 yuan per year ; The price of cloud hard disk backup is reduced by 50% to 7.2 yuan per year.
Tianyi Cloud has launched a promotional slogan of 90% discount on core products and as low as 10% discount.
Judging from the current observation, this wave of price cuts is a real drop. No matter what the thinking behind the manufacturers is, it is a real good opportunity for enterprises that want to deploy cloud computing services and equipment.
There are too many products, so I won’t describe them more. You can consider the cost performance
Of course, in addition to equipment, many improvement books and courses have discounts at the lowest price throughout the year, and you can also pay attention to it to improve your personal technical ability.
Here is a friendly list of books recommended by Lao Yang. You are welcome to buy them during the time period of 618: " 2023 Must-Read Book List "
